COPYING-MACHINE.

Application filed. November 25, 1913.

To all whom it may concern: v

Be it known that I, RICHARD BERGER, a

d subject of the King of Bavaria, and residing copying paper drawn off aroll, the control of the auxiliary mechanisms by the copying paper beingsuch as to cause the starting and stopping of any of the said mechanismsto be dependent on the movement of the copying paper and in accordancewith actual requirements. For this purpose a feeler or equivalent deviceisprovided which comes into operation with varying sizes of papers forcopying, the actuating of the feeler not being dependent on apredetermined number of revolutions of a part of the machine, say thecopying roller, but being dependent on the length of the sheets. i

In order to use the copying paper from a storage roll for actuating thefeeler, the former'is provided with marks or perforations, at suitabledistances apart, into or with which the feeler can engage. The

thin copying paper is not strong enough to transmita more or less greatforce. This difficulty is overcome by causing the copying paper, withwhich-thefeeler is in contact without producing any appreciable effortthereon, to impart a slight motion to the feeler of such a nature astorequire no effort on the part of the copying paper. For example,gravitation can be utilized so that the first. slight motion of thefeelercauses the latter to be coupled direct or through interveningparts with the mechanism to be set in motion by the. copying machine,while at the same time the feeler is allowed or caused to return to itsinitial position.

The improvement is shown .in the annexed drawings, in which: 1

Fig. .3 a detail and Fig. -,4 a perspective view of the copying paper inconnection with the controlling mechanism.

The copying-strip 1, drawn off the roller 2, passes over a roller 3through the water bath 4 to the copying rollers 5, 6 and 7 TheSpecification of Letters Patent.

driving movement is imparted to the roller 7 and when the latter ispressed in the known manner against the roller 6 rotation is transmittedby friction to the rollers 5 and 6.

Between the table 8 and the paper 1 there is a constantly revolvingshaft 9 and a parallel shaft 10 is driven through the intervention ofgear wheels 9 and 10 (Fig. 2).

On the shaft 9 is fast a grooved friction,

wheel 11, and on the shaft 10 is mounted a loose wedg-e-shaped wheel.12formed with a peripheral recess 13 which in the position shown in Fig. 1interrupts the conection between these wheels. The wheel 12 is held inthis position through the intervention of a feeler-arm 14 on the sleeve12 of said wheel 12 (Figs. 2 and 4.) The feeler rests upon the paper'lin the path of perforations 15 therein. When a perforation advancesbeneath' the feeler, the latter enters same and so causes the wheel 12to turn until its Wedgeshaped circumference engages in the groove;

of the wheel 11 and is then rotated by the latter. The wheel 12turns-until it is again in the position shown in Fig. 1 when the feeler14 comes to rest on the surface of the paper, until it subsequentlydrops into another perforation. a

the shaft 10 is fixed a chain wheel 16 which by a chain is connectedwith a chain wheel 17 loose on the shaft 18. (Fig. 1). A furtherchain-drive 20 imparts motion in the known manner to a wheel 19 loose onthe shaft of the copying roller 7. From here another chain-drive 20passes to the roller 21.

The chain wheel 17, loose on the shaft 18,,

is connected with a grooved wheel 22 (Fig.

3). :On the shaft 18 is fixed an arm 23 which and 3). 7

When the feeler 14 drops into a perforation 15 of the copying paper, andthe loose wheel 12 is taken around by the constantly rotating groovedwheel 11 in the manner previously explained the feeler-arm 14 causes thebellcrank 29, 30 to stving and to the shaft 18 with it. The shaft 18lets the feed device 31 make one revolutionand this mo-- tion may beutilizedto, set in motion ,any
